Duane, important is to set fine tuning (1Hz) when using the APF as the only precise tune on spot will effectively pulling out this weak sig from the noise. I do not understand why the K3/K3S never got as same feature as KX3 > switching to fine tuning automatically when APF is ON...
Also try to reduce RF gain (do not keep it at max) in order to reduce noise. ----- 73 - Petr, OK1RP "Apple & Elecraft freak" B:http://ok1rp.blogspot.com MeWe: https://bit.ly/2HGPoDx MeWe: https://bit.ly/2FmwvDt -- Sent from: http://elecraft.365791.n2.nabble.com/ ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
